2.4 Coal Effect Layout
NOTE: Due to the nature of the product, the Burner Tray shape and therefore the
coal layouts will vary. Therefore the following examples demonstrate the
principles of the fuel layouts that should be followed and should not be regarded
as literal.
This fire is supplied with different sizes of
ceramic coal, with the quantity supplied
being dependant upon the size of the burner.
Proceed with the coal layout as follows: -
1. With reference to
Figure 14
,
Figure 16
or
Figure 18
unpack the
small square
coals
and place them along/around the
burner tray leaving equal spaces
between them, taking care not to cover
any gas ports.
2. Unpack the
aeration tubes
, and place
them on the shaded parts of the burner
board.
3. Unpack and carefully place the
medium
square coals
(if supplied) around the
perimeter of the burner tray so that they
are touching each other. Ensure that the
first coal on each side is set back a
minimum of 50mm (2”) and that no slots
or gas port holes are covered. There
may be more
medium square coals
than required. In this instance use only
sufficient coals to go around the
perimeter as indicated.
4. Unpack
the
random coals
and proceed
to bridge them across the aeration tubes
and previously laid fuel. Start by
bridging from the front row back onto the
aeration tubes, then across the aeration
tubes, then from the aeration tubes out
to the outside layer of previously laid
coal. This will create the second layer of
coals.
NOTE: No part of this second
layer should come into direct
contact with the burner board.
5. The remaining coals may now be placed
at random to form a third layer.
Packing the coals too tightly together will
result in a poor flame picture. The best
results come from a ‘loose’ fuel build.
Do not place any coals immediately over the
pilot assembly.
After the appliance has been allowed to
warm up, small adjustments (using a small
pair of tongs) may be made to the top layer
to achieve the desired flame picture.
It is recommended that the coals be left
alone once the desired flame picture has
been achieved.
Constant moving of the
coals causes the coals to disintegrate
and/or cause discolouration.
WARNING: Do not touch the
fire when it is alight. The fire
will remain very hot for a while
after extinguishing.
